Specification of Letters Patent.

Patented July 2, 1912,

Implication filed January 30, 1812. Serial No. 874,305.

To all whom, it may concern:

lie it known that I, Snvnno Camro Flu-roost), a subjectiot' the Kin of Italy, and residing at-I-Ielcnsburgh, umbartonshire, Scotlanmh'hxive invented a certain new and useful Improvement in 'Wheels, of which the following is a specification.

'lhisinventioh hasfor its object to provide an improved construction of wheel a plieable, to each individual wheel of 0rd nary road vehicles as hereinafter particu-' larly described and pointed out in the claim. In the accompanying drawings Figures 1 and 2 are elevations at right angles to each other of a rear wheel of a motor road vehicle embodying th e invention. I

Referring todthe drawings, the ground tread surface for the vehiclewheel' A which,

may be provided with a solidrrubber tiroD, comprises a contlnuous bandj B er; flexible prevcnt skidding-and provide "if desired with an outer coating of rubber, said hoop or band surrounding said wheel, and being distended into approximately elliptical shape and sli htly flattened on the round by means of the plurality of guides ormed for instance by two flanged pulleys or rollers O. The band B is maintained in 'position and in the plane of the wheel A by means of the said flanged rollers C and b a pair of vertical rollers E. The rollers C are rotatablymounted, within the area inclosed by said hoo or band, for example on brackets IF ,whic l are pivoted at G on.

clamps H secured to the ax e bearing'I and are connected together by means of a-eprin J, sto s K adapted to engage with one 0 said c amps, as atL'," serving to" limit the movement of the brackets F toward each other under the action of said spring'J As shown, the vertical rollers E are carried by a bracket M secured to the at N and O. A secured to the vehi ner. v 7 It will be understood that durin rotation of the vehicle wheel A the end ess', band B travels around said wheel, contacting with the wheel and also contacting with the rollers G and E. which retain their posibody in knownymani tion relatively to the axle of the wheel. It

will also be seen that the point of interstantially coincident with the center of the wheel.

' Having now described my invention what I claim and desire to secure by Letters ent of theUnited States is The combination with a vehicle wheel: of

endless band arranged in the plane of the clamps H ud guard P may be,

section of the axes of the ellipse is sub:

wheel and adapted to travel around the same in contact with the wheel and-with the ground the clam s secured to the axle hearing at the whee, brackets ivoted to said clamp,

asprin connectingt obrackets, and aides on the rackets engaging the band an serving to distend the band into approximately elliptical form and .to maintain the band in the plane of the wheel.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
